安平桥
How could one bridge enlarge the commercial territory of a port city?
Anping Bridge crosses the former bay between Anhai in Jinjiang and Shuitou in Nan'an, about 30 kilometres southwest of central Quanzhou. Built from 1128 to 1152, it carried the main road south towards Zhangzhou and Guangzhou. Its historical name Five Li Bridge refers to a traditional measure of length rather than a precise modern kilometre count.
The surviving structure extends roughly 2,255 metres and is carried on 360 stone piers. Rectangular, pointed boat-shaped and double-pointed piers respond to different water conditions, while granite beams between five and eleven metres long form the deck. Builders adapted methods already used at Luoyang Bridge to an even longer crossing.
Anping was also a social landscape. Monks, merchants, officials and residents contributed to construction; pavilions, shrines, small pagodas, repair inscriptions and stone guardians served travellers along the route. Silting, reclamation and later repairs have changed the watery setting, so the bridge must now be read through both surviving masonry and a reconstructed coastal geography.
